Diaphragm Pumps: Maintenance Tips
Diaphragm Pumps are used quite predominantly in a wide range of industries and can deal with an extensive selection of liquids. These types of pumps, specifically, can transfer liquids with low, medium, or high thickness. Likewise, diaphragm pumps can also endure many aggressive chemicals because these pumps can be constructed with a wide variety of materials and diaphragms. Follow along, as we will walk through helpful maintenance tips and tricks when utilizing a diaphragm pump.
HELPFUL PROCESSES FOR A CORRECT USE OF THE DIAPHRAGM PUMP
Inspect your pump and confirm that the hydraulic system shows no signs of wear or clogging. Additionally, check and determine that connections are tight, and the pump is properly secured.
Reminder: Keep constant control over the oil level. The overall performance of the diaphragm pump relies on perfect lubrication. So, without this, the operation of the individual components will function improperly.
After each use, it is good practice to run clean water inside the pump. This will allow any residue, of chemical products, to be completely removed from the suction filter.
Winterizing: A special operation should be carried out right before storing the pump for the winter season. For example, flushing RV anti-freeze liquid through the pump and emptying the manifolds. Check out our blog for a step-by-step guide on how to winterize a Comet Pump!

ROUTINE PUMP MAINTENANCE
As previously mentioned, routine maintenance should be carried out on a regular basis. To make things easier, we broke this down into three main phases. In phase one, you will need to drain and flush the pump with clean water before disassembling and servicing your diaphragm pump. Next, in phase two, you will need to fit a new set of diaphragms. Lastly, phase three consists of inspecting the valves and changing the oil. Below, you will find a thorough, 10 step guide on how to properly maintain your diaphragm pump!
STEPS TO PROPERLY MAINTAIN YOUR DIAPHRAGM PUMP
STEP ONE: Remove all oil from the inside your diaphragm pump and completely remove the pump head.
STEP TWO: Take off the diaphragm and position the axial sleeve hole upright. Then position the piston at its highest point.
STEP THREE: Next, thoroughly grease the internal hole of your diaphragm pump.
STEP FOUR: From here, you will need to rotate the pump shaft until the diaphragm is on the piston. Screw on tight.
STEP FIVE: Now, grease the new gaskets and replace the previous ones on the head.
STEP SIX: After you complete the greasing, you will need to rotate the shaft, bringing the piston downwards. Now, mark it.
STEP SEVEN: Once the outside of your diaphragm is greased, you will want to reposition the head by tightening the four screws using a torque wrench.
STEP EIGHT: Completely remove the valve cap, valve, and gaskets. Replace all components (if need be) and reinstall.
STEP NINE: To fill your diaphragm pump with oil, you will need to tilt your pump to one side, letting the air escape. At this point, rotate the shaft, tilt the pump, and wait for about 60 seconds for the air to escape.
STEP TEN: Lastly, repeat this process on all other pistons. Remember to fill your pump with the correct amount of oil.
